This new model with a patented ceramic actuator face expands SCHURTER’s MSM family of metal pushbutton switches with rugged background illumination over the full actuator surface. The material is resistant against scratches, abrasion and impact as well as chemicals and makes the unit well suited for many applications in medical technology and industry. 

The new MSM CS metal pushbutton switch from SCHURTER is equipped with an actuator made of rugged ceramic. Ceramic is being employed for the first time in an operating switch and is patented by SCHURTER for this application. The material is resistant against scratches, abrasion and impact as well as chemicals; it can also be labeled and is translucent. Equipped with these versatile features, the MSM CS pushbutton switch opens up completely new possibilities in the construction of medical equipment and in industry.

If the switch is not illuminated, the actuator surface is white. Standard or customer-specific lettering is in black and embedded directly into the ceramic material.

In the illuminated versions of the switch, the actuator face fully illuminates across the entire surface, and lettering and symbols can also be applied. Positive lettering is done in black; for inverse lettering, the label text appears in the selected illumination color. Because of the way they are made, the labels are scratch-proof and stand up to common cleaning agents.

Thanks to a small, low-profile front mounting of 1.7 mm, the IP69K protection class and high level of impact resistance, the switch is extremely robust and protected against vandalism. The MSM CS is available for mounting diameters of 19 and 22 mm. Various contact types cover a range for allowable switching voltages from 30 VDC to 250 VAC; allowable switching currents range from 0.1 to 10 A. For fast wiring, the MSM CS provides blade terminals. Wires are connected to the microswitch element, which is subsequently snapped onto the previously screwed-in switch housing.

Where the need to control lighting, temperature or other functions according to daylight hours exists, Finder has developed an innovative, easily programmable time switch which employs a unique digital program to calculate sunrise and sunset times by simply entering the location’s postcode with a single joystick.

With ever increasing pressures to reduce energy consumption, Finder’s Astro 12.81 time switch will control lighting, heating/cooling and humidity equipment in commercial, residential and industrial applications wherever sunrise and sunset times are critical in determining operational times. The Astro’s micro-controller stores postcode data from 16 European countries, including the UK, allowing for a precise calculation of seasonal sunrise and sunset times through date and location coordinates. The Astro is also programmable using geographical coordinates, settable between 30°S and 64°N; 16°W and 50°E. The Astro will also automatically compensate, should European Summer Time be enabled.

For added flexibility, the output switching can be advanced or retarded about the calculated sunrise (or sunset) time in 10-minute increments—up to a maximum of 90 minutes. A manual override of the output status allows for maintenance or one-off events. With a 16A 250vac rated output contact and a 120A 5ms peak current rating, the Astro time switch is capable of directly switching 2000W halogen, 750W compensated fluorescent, 200W CFL or LED lamp loads and AC15 loads up to 750 VA.

The integral back-up battery, which is easily replaceable from the front, features an automatic power save mode which helps extend battery life.

UP1 Undervoltage Release Switch for Operators Safety

The new UP1 undervoltage switch monitors the supply voltage and actuates a trip release when there is an intense drop in voltage or when the supply voltage is interrupted. As soon as the supply voltage returns in full, the machine or equipment does not automatically restart in an uncontrolled manner, but must be consciously switched on again. Using this function, dangerous situations for operating personnel as well as for the surroundings of the device itself can be prevented.

The UP1 is a 2-pole circuit breaker with additional undervoltage monitoring actuates a trip re-lease with a loss of voltage or an intense voltage drop. The breaker is available with rocker actuation for snap-in mounting or with push-button actuation for both snap-in mounting as well as screw fitting. Protection covers against the ingress of dust and spray water make the use of the breaker in harsh environments such as wood-, masonry- or metal-workings possible.

The requirement for the use of undervoltage protection is in existence for applications such as gardening equipment, gardening shredders, floor cleaning and sanding devices, electrical tools such as circular saws, band saws, grinding machines and drills. Further examples are fuel pumps, coffee-milling devices, fruit juice squeezing machines and fruit juice centrifuges.

The UP1 undervoltage circuit breaker is configured differently in its hardware for various net-work supply voltages und must be therefore ordered for the appropriate supply voltage. Rated switching category is AC-1 16A / AC-3 14.5A @ AC 240 V. The breakers are approved to IEC 60947, UL 508, CSA 22.2 No.14-95 and also contain a horsepower rating.

Technical Characteristics:
- 2-pole switch
- Undervoltage trip release with restart prevention
- Available with rocker or push-button actuation
- Dust and jetting water protection to IP 65
- VDE & cURus approvals for rated currents AC-1 16A / AC-3 14.5A @ AC 240V

Bulgin announces new version of MPI range of illuminated vandal resistant switches.

All MPI switches have bodies and buttons machined from high-grade stainless steel. A tough Polycarbonate lens in the stainless steel actuator gives a robust and aesthetically-pleasing switch.

All switches are front-panel sealed to IP66. However, Bulgin’s new range is also rear-of-panel sealed. This makes them suitable for use outdoors or in other situations where condensation or leakage behind control panels can be problematic. Rear panel sealing is available in a variety of styles, including single and dual colour with dot or ring LED illumination. Independent switch and LED terminals allows customers the flexibility to choose between permanent or controlled illumination. Contacts are single-pole push-to-make.

“The MPI series of switches boast IP66 sealed properties combined with a rugged design and a variety of style options,” comments John Wilson, MD of Elektron Technology. “With this latest addition to the Bulgin range Elektron Technology further enhances its complete design-and-manufacture service, offering our customers across a number of industries a flexible, quality solution to meet their control panel design needs.”

The switches have either solder tags or screw terminals, which facilitates easy field servicing, and also feature potted moulding and flying leads to the rear of the switch. With integral supply resistors the LEDs can now be driven directly from 6, 12 and 24V supplies.

The MPI series is tested to 750,000 mechanical and 35,000 electrical operations and rated at 50mA, 24V dc. The series has also recently undergone design improvements at construction stage, incorporating surface mount LEDs and TVS’s.

All switches in the MPI series have momentary action contacts making them ideal for access control and door entry applications including lifts, panic buttons, car park barriers, emergency telephones, vending machines and food processing.
