Filed: 1970-03-26
Abstract: 1304277 Retractive switches CRAIG & DERRICOTT Ltd 19 April 1971 [26 March 1970] 14702/70 Heading H1N A switch has both snap-acting and positivelyactuated contact members operable by a common operating member. As shown, a retractive plunger 2 carries a leaf-spring bridging contact member 16 secured between collars 9 and 18 and having two tension springs 17 whereby depression of plunger 2 causes the contacts 14 and 15 to snap away from fixed contacts 11 and 12. Additionally a rigid bridging contact plate 21 is carried by an insulating assembly 23, 24, which is axially slidable on plunger 2, and normally bridges fixed contacts 10 and 13. After a preset amount of lost motion of plunger 2 a collar 26 thereon engages the part 23 and thus opens contacts 10, 19 and 13, 20. The relative disposition of parts is preferably such that the snap-acting contacts 14, 15 are opened before the positivelyactuated contacts 19, 20, but the two actions may be in the reverse order or simultaneous. The plunger 2 may be formed in two structurally separate parts, one slidable in socket 7 and subject to retraction spring 8 and the other slidable in a wall of the housing 1. In a second embodiment (Fig. 4, not shown) common fixed contacts (10a and 13a) are provided between the plate (21a) and leaf spring (16a) and the both sets of contacts are normally open. In the embodiment of Fig. 5 the positively actuated contacts 19b, 20b form the "fixed" co-operating contacts for snap contacts 14b, 15b and if initial movement of plunger 2b does not snap the contacts open then a collar 26b positively moves contacts 19b, 20b while projections 29 of housing 1 prevent contacts 14b, 15b from following. To connect the contacts of this embodiment into an external circuit flexible connections (not shown) would be provided.

Speed signal.-A sinusoidal magnetic pick up 8 feeds, through a limiter 9, a mono-stable circuit 10 producing constant pulse amplitude and width at a frequency proportional to speed, converted to a speed-responsive D.C. voltage VROAD in an averaging circuit 12. In Fig. 3 (not shown), the speed signal is obtained by a radar circuit using a Gunn diode emitter. Torque siqnal.-The load signal voltages VREF1, VREF2 are derived from a potentiometer operated by a capsule 21, subject to the absolute pressure in the engine intake manifold, with a barometric compensator 21a; or to manifold depression, modified by engine throttle setting; or to engine throttle setting alone, feeding the comparators 13, 14 through adding circuits 15, 16 and arranged so that upshift occurs when VROAD just exceeds VREF1 or VREF2, the former being lower than the latter so that 1-2 upshift precedes 2-3. The manifold pressure transducer 21 produces a voltage VVAC which is modified by engine throttle setting to produce a voltage ranging linearly with throttle setting; light throttle setting being determined by constant voltages VLT1 and VLT2; full throttle by VLT1 and VVAC, VLT2 and VVAC. A kickdown throttle switch provides a higher voltage VKD1, VKD2. Feedback resistors 22, 23 provide hysteresis, and a power supply 35 provides stabilized input voltages. Servo pressure may be subject to intake depression by loading a pressure relief valve. Road speed is indicated to the driver by a moving coil meter 25, and total distance travelled by a stepping solenoid 29 energized by one-tenth mile pulses through a divider circuit 27. Reverse is provided by a manual switch 31 energizing a solenoid 32, and the switch may have two additional positions raising to full voltage VREF1, and both VREF1 and VREF2, which inhibits upshift above second and first ratios respectively.
