Continuous operation switch

Dauerlaufschalter

Interruptor para funcionamiento continuo

Interrupteur de fonctionnement en continu

On/off switches are manually operated by compressing a rocker spring, i.e. the user has to overcome the spring tension in the on-position and hold the switch in that position for the duration of the entire operation (dead man?s switch). In the case of extended operation this can be rather tiring. A mechanically locking catch can provide a solution and keep the appliance switched on. Drills in drill stands require this continuous operation switch. Other electric power tools must not be equipped with this continuous running switch in order to reduce the risk of accidents. In cases like this a dead man?s switch is required.
