Switchoff-Timer  for battery-powered devices

Bild Ausschalt-Timer

Battery powered devices with normal on-/ off-switch (snapping button, slide-, rocker-, rotary-switch) can be updated with this small electronic board. Then the battery-powered device switches off after a certain time (1 - 120 minutes, specified with your order) and the battery will not be discharged.

The device is switched on normally with the switch. Then the device runs as usual, but switches off automatically after the specified time. To turn it on again, the device must be first switched off and then switched on again.
