The greatest advantages of mechanical position switches are their robust design and their high switching current carrying capacity. They are generally switched via a cam or a switching lug, which actuates the sensor plunger, which then closes the electric circuit. Thanks to their high operational temperature limits of about 80 °C (176 °F) (in special cases even up to 180 °C (356 °F), they are outstandingly suitable for particularly difficult environment conditions, for example foundries.

For high operating frequencies it is necessary to check whether the associated mechanical wear will have any effects on functionality over the entire period of operation.
