Yes, that's a typical design. The first of the two products I linked to is like that. > The range of movement was rather small but > after thinking about it may be enough to get the jaw to open. A lever will increase the travel. Or just find a different solenoid with a longer travel. If you don't need a lot of force, and have a solenoid with a removable plunger, you can stretch beyond the manufacturer's travel specification, but I believe the force decreases following the inverse square of the distance. Automotive door look actuators can be a good source for fairly long travel solenoids (technically I think some are motors). This one: http://www.amazon.com/HIGH-POWER-DOOR-LOCK-ACTUATOR/dp/B0002KR9PW has 3/4" travel, and instead of using a spring return you reverse polarity. -Tom _______________________________________________ Hardwarehacking mailing list [email protected] http://lists.blu.org/mailman/listinfo/hardwarehacking
