The SW-100 is a zero force replacement for mechanical push buttons that are commonly used in two hand control safety applications. It features a comfortable, ergonomic design that allows for multiple mounting configurations to achieve optimum application coverage.

Fully configurable operation indicators add to the functionality of the switch by offering visual feedback to the operator with respect to the process status. Long life PhotoMOS outputs coupled with a virtually indestructible casing make the SW-100 a perfect addition to any machine safety program.


Greater convenience with less stress on the hands.
Inventive start-up switches in accordance with ergonomics. [SW-101]



Reduction in false operation from dropped objects [SW-101]

The response time is set for a slight delay so that the switch will not respond a falling object, such as a dropped tool. The switch is designed so that it will operate when touched by hand, but false operation will rarely occur when something is dropped onto it.



A switch that pursues the prevention requirement for malfunctioning as required by ISO 13851 (JIS B 9712) two-hand control devices [SW-111]



Safeguard prevents false operation

SW-111 saves the hassle of making an additional safeguard. In addition, with its ISO 13851 complying shape, even a knock on the elbow will not cause a false operation (light interruption).



Intended startup is possible [SW-111]

SW-111’s detection does not operate when a hand is just placed onto the unit.
With a design that only detects when fingers are bent in and lightly grip onto the unit, an intended startup is



Equipped with external input indicators

Two sets of external input indicators (two colors) are provided, so that they can be used as operation indicators for a variety of purposes.



Prevents false operation caused by dirt

If the light is continuously interrupted for more than 10 sec. by dust, etc., the switch is disabled and the fault indicator (yellow) illuminates.

Uses a long-life Photo-MOS relay

Because a Photo-MOS relay is used for the output, a single unit can be configured without a specific output polarity.
In addition, there is no need for periodic replacement of parts such as contact-type relays.
