PURPOSE:To prevent a detecting unit from being unintentionally operated by simultaneously resetting the unit by a reset operating means. CONSTITUTION:A signal generating means detects the current, the voltage of an electric circuit to generate a signal in response to a state. A detecting unit 1 has output means 14 and resetting means 6, and operates the means 14 when the signal of the generating means becomes a predetermined state. A power source unit 2 supplies power to the unit 1. A housing stores a plurality of units 1 and 2 to easily mount them on a control panel. The front cover 4 of the housing 3 prevents dusts from invading into the housing 3 and prevents hands from unintentionally contacting the shaper of the unit 1. Reset operating means 8 supplies a reset signal to the means 6 of the unit 1 to return the means 14 to an initial state. |
