Switch conversion apparatus
A switch conversion apparatus including an interface device, a mounting plate configured to mount to a toggle switch and including at least one aperture for receiving a toggle arm of a toggle switch, and an actuator plate configured to slidably engage the mounting plate and including at least one aperture for receiving and engaging a toggle arm of a toggle switch when engaged by the interface device so as to transition the state of the switch. Other embodiments of a switch conversion apparatus include one or more mechanical, electrical, and/or pneumatic timers.
1. A switch conversion apparatus, comprising:
an interface device;
a mounting plate configured to mount to a toggle switch and including at least one aperture for receiving a toggle arm of a toggle switch; and
an actuator plate configured to slidably engage the mounting plate and including at least one aperture for receiving and engaging a toggle arm of a toggle switch when engaged by the interface device so as to transition the state of the switch;
a pneumatic timer including a cylinder, a piston, at least one valve, and a timer interface configured to communicate with the piston;
a yoke attached to the actuator plate;
wherein the interface device is a slider and is further configured to engage the timer interface so as to displace the piston and the yoke so as to displace the actuator plate.
2. A switch conversion apparatus, comprising:
an interface device;
a mounting plate configured to mount to a toggle switch and including at least one aperture for receiving a toggle arm of a toggle switch; and
an actuator plate configured to slidably engage the mounting plate and including at least one aperture for receiving and engaging a toggle arm of a toggle switch when engaged by the interface device so as to transition the state of the switch;
a link configured to communicate with the interface device;
a yoke configured to communicate with the link and the actuator plate;
a pulley including a cable having a first end and a second end wherein the cable is attached at the first end to at least one of the slider, yoke, link, and actuator plate;
a cylinder including a first end and a second end and further including at least one valve disposed toward the first end;
a piston disposed in the cylinder and configured to attach to the second end of the cable;
a spring retainer disposed at the second end of the cylinder; and
a spring disposed in the cylinder and between the piston and the spring retainer.
