Abstract
1,218,343. Attracted armature relays. SEEMARK SWITCHES Ltd. 9 Aug., 1967 [9 May, 1966], No. 36650/67. Divided out of 1,218,342. Heading H1N. An electromagnetic relay has a coil former or bobbin 31 having one end cheek 30 formed as a printed circuit board through which one end of the relay core 40 passes to co-operate with an armature 38 pivoted at 37 on an L-shaped yoke 35. A contact 4 on an armature extension 39 moves between fixed contacts 43, 44 and is biased against the latter by a leaf spring 50 engaging the other end of the armature. The relay coil is connected in a circuit including a transistor 52, capacitor 53 and resistor 54 all of which are supported from the board 30 and connected to printed circuit elements thereon. A two-part plastics casing (not shown) may be mounted to enclose the relay, the casing part on the armature side of the board at least being translucent to admit light to a photo-electric cell (not shown) spaced from the relay armature and mounted within the casing.
