Claims19
A spring for an electrical switch, comprising:
- a contact arm having a contact member;
- and
- a base from which the contact arm extends, the base having a terminal and an extension extending from a remaining portion of the base not consisting of the terminal and the extension in a direction away from the contact arm, the spring provides a current path extending from the contact member through the remaining portion of the base including the extension and to the terminal, the contact arm and the base having a constant cross-sectional area along the current path in both a pre-bent state and a bent state of the base, a smallest cross-sectional area of the contact arm in a direction perpendicular to a longitudinal direction of the contact arm is equal to a smallest cross-sectional area of the remaining portion of the base including the extension in a direction parallel to the longitudinal direction of the contact arm.
