Definitions
- the safety snap switch has two leaf springs which run essentially parallel to one another and are each clamped at one end, one of which is bent approximately hook-shaped at its free end, while between the hook-shaped end of a leaf spring and the free one At the end of the other leaf spring of the safety snap switch there is an omega spring.
- the leaf springs of the safety snap switch are fastened with their clamped ends in a metal strip which is firmly seated in the housing and is designed as a plug outside the housing.
- the spring tongue 38 In order to set the lower switching point of the snap switch or its actuating force, at which, in the case of a vertically directed force on the spring tongue 38, the movable contact 32 jumps from the lower fixed contact 50 to the upper fixed contact 52, the spring tongue 38 has one in its front section for reasons of illustration, there is an opening which is not visible and through which an approximately cylindrical extension 58 of an insertion piece 60 projects, which has a larger diameter than the opening and which bears against the spring tongue 38 from below.
- the insert 60 is in a helical spring which is supported at the other end on an adjusting screw 62 screwed into a corresponding thread in the base 4.
- the spring tongue 38 carries a corresponding small insulator 89, for example in the form of a plastic rivet, in the region of the intended contact point with the leaf spring 74. If the pressure on the membrane 10 continues to rise, the spring tongue 38 and the leaf spring 74 are now simultaneously moved downward after the plastic rivet 89 abuts the leaf spring 74, the hook-shaped bent end of the leaf spring 74 reaching a position after a certain downward movement, in which, due to the action of the omega spring 78, the leaf spring 72 with the movable contact 80 arranged thereon is pressed upward against the fixed contact 84 located above it, so that a circuit is formed over the plug formed by the metal strip 76 and the plug formed by the metal strip 28 can close and in the device controlled by the switching device 1 triggers a safety circuit, for example switching on the pump motor.
- a safety circuit for example switching on the pump motor.
