Abstract: A push button switch (1) includes an insulative housing (2), a cover (3), an actuator (4), a common contacting contact (5), a non-common contacting contact (6) and a movable contact (7). The cover engages with the housing and defines a guiding hole (311). The movable contact is received in the housing and includes a connecting portion (77), a supporting portion (76), and a pressable section (74) connecting the supporting portion. A non-common contacting contact is mounted in the housing and has a non-common contacting strip (63). A common contacting contact is mounted in the housing, includes a common contacting strip (53), engages with the connecting portion of the movable contact and is movable with the movable contact to touch the non-common contacting strip, thereby electrically connecting with the non-common contacting contact.

Abstract: A detect switch (100) includes a cover (2), a spring (3), a slider (4), a pair of movable contacts (5), a dielectric base (6) having a post (611) projecting from a bottom wall (61), an actuator (7) and a number of fixed contacts (8). The cover is formed from a planar metal sheet and is substantially rectangular and has a protrusion downwardly projecting therefrom and defining socket (21) therein. The slider defines an elongate trough (41) in an upper surface thereof for receiving the spring. The movable contacts are mounted under the slider and each have an arch-shaped configuration. The dielectric base has a periphery wall enclosing around the bottom wall and a cutout (621) defined through the periphery wall. The actuator comprises an upright columnar main body, a stopper arm (71), an actuating arm (72) and a guiding camber (74).
