Switch (Toggle, Rocker and DIP)Latching SPST on-off switch

A toggle, rocker or DIP switch latches: it stays in the position it was put in until it is moved again. Used as an on-off switch it connects or disconnects two terminals, so a circuit can be powered, enabled or configured without a program holding it. The six switches here run from 50 mA to 20 A. The CTS 206 DIP switch carries only 50 mA at 24 V DC switching: a DIP switch sets configuration bits, never power. The KCD11 rocker carries 1 A at 250 V AC, the E-Switch 200 and 100 toggles 3 A at 120 V AC or 28 V DC and 5 A at 120 V AC or 28 V DC, the C&K 7101 toggle 5 A at 120 V AC or 28 V DC, and the E-Switch ST4 20 A at 6–30 V DC. Contact resistance runs from 10 mΩ (the C&K and E-Switch 100 toggles) to 100 mΩ (rocker). The toggles and the rocker are panel parts: they mount in a front panel and are wired to the board, so their PCB footprint is a 2-pin header. The DIP switch solders straight into the board. The page, ProTech and the footprints number the terminals 1 and 2; the third terminal of the SPDT toggles is not used for on-off. ProTech’s LED toggle switch (small, medium, large) is the E-Switch 200, 100 and ST4; its lit tip is ProTech’s display of the position, the real bat is plain.
