A sealed pushbutton switch, comprising:
- an insulative housing defining a cavity;
- an actuator movably retained in the cavity of the insulative housing;
- a base conglutinated to the insulative housing and having a plurality of slots defined near sides thereof for retaining glue;
- a plurality of fixed contacts assembled to the base;
- a spring compressed between said actuator and the insulative housing;
- and
- a movable contact provided with a plurality of contact portions and being movable with the actuator from a first position where the contact portions are in contact with corresponding fixed contacts to a second position where the contact portions disengage from the fixed contacts.
A sealed pushbutton switch comprising:
- an insulative rectangular housing defining a cavity and a full opening on a first side and a circular through hole in a second side perpendicular to the first side;
- a base attached unto the first side and covering the first opening;
- a plurality of fixed contacts secured to the base;
- an actuator movably retained in the housing;
- and
- a movable contact associated with the actuator and movable between a first position where the movable contact is engaged with the fixed contact, and a second position where the movable contact is disengaged from the fixed contact;
- wherein
- at least one glue retaining slot is formed along a portion of a periphery of at least one of said base and said housing so as to retain glue therein when said base and said housing are fastened together by said glue.
