ABSTRACT:
Disclosed herein is a plunger switch for electric appliances, which is mounted to an electric appliance to control a lamp, a motor, a heater, etc. and has enhanced safety and electrical and mechanical properties, thus maintaining the original condition of the switch without reduction of elasticity or deformation of the switch, even if the switch is repeatedly used. Thereby, the operational reliability is increased and malfunctions caused by arc discharge are prevented. Unlike the sliding structure which does not use another separate contact point, this invention can be adapted to a high-current or high-temperature switch. Further, this invention has a hook, thus allowing easy assembly and replacement of the plunger switch to a proper position on an electric appliance.
