Abstract A timer having switches are responsive to a cam, the cam being driven through a timer motor through a clutch. The cam and the switches are disposed within a housing. The switches include electrical contact blades with cooperating electrical contacts. Electrical terminals are mounted in the housing and extend through the housing and are unitarily constructed with the switches to form a one piece combination. The electrical terminals are held within slots in a wall of the housing through a pair of projections lanced from the terminals which engage notches opening to the slots. The projections are individually in planes that are at an angle to each other such that their distal ends are directed away from each other and which are spring biased to act as cantilevered spring members and made to squeeze inwardly between sides of the notches. In the preferred configuration, the projections are pointed to act as barbs that dig into the comparatively soft plastic walls of the notch and tend to anchor the combination blade terminal in place.
In a timer having motor driven cam means and switch means responsive to said cam means both of which are disposed in a housing: at least one combination electrical contact blade having a contact thereon and an electrical terminal extending into said housing and electrically connected to said switch means, at least one slot in a wall of said housing receiving said electrical terminal, a notch in said wall opening to said slot, and at least two projections lanced rom said electrical terminal, said two projections individually in planes that are at an angle to the other such that their distal ends are directed away from each other and spring biased to act as cantilevered spring members and made to squeeze inwardly and into walls of said notch.
