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

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'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 possible.

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.
