A low current motor protector ( 10, 10 ') has an oblong metal housing ( 12 ) defining a switch chamber and formed with an open end. The housing has opposing flange portions extending transversely from the open end. Spaced apart lid portions ( 18 a, 18 b; 18 a', 18 b') are received on and clamped to the flange portions with an electrically insulating gasket ( 16 ) having a central opening interposed between the housing and the lid parts. The lid parts are formed with a recessed ceramic heater seat disposed in the switch chamber having spaced apart contact shelves ( 18 f) which receives a ceramic heater ( 20 ) which is maintained in place and provided with contact force by a spring clip ( 22, 22 ') attached to one of the lid parts. A thermostatic switch is mounted in the housing and has a movable electrical contact movable into and out of engagement with a stationary electrical contact on one of the lid parts.
