摘要： An apparatus in an electronic control system allows two or three wire operation. A power supply can supply power to the enclosed circuitry in both two and three wire installations. Two separate zero cross detectors are used such that timing information can be collected in both two and three wire installations. Both zero cross detectors are monitored and are used to automatically configure the electronic control. Over voltage circuitry senses an over voltage condition across a MOSFET which is in the off state and turns the MOSFET on so that it desirably will not reach the avalanche region. Over current circuitry senses when the current through the MOSFETs has exceeded a predetermined current threshold and then turns the MOSFETs off so they do not exceed the MOSFETs' safe operating area (SOA) curve. Latching circuitry is employed to keep the protection circuitry in effect even after a fault condition has cleared. Lockout circuitry is used to prevent one protection circuit from tripping after the other circuit has already tripped from a fault condition. The protection circuitry output is desirably configured such that it can bypass and override the normal turn on and turn off impedance and act virtually directly on the gates of the MOSFETs. Preferably, the system has a high efficiency switching type power supply in parallel with a low frequency controllably conductive device.

摘要： A variable resistance control device and switch has a base, made of insulating material, a rheostat, mounted to the base, and a switch, mounted to the base. The rheostat includes a variable resistor trace, positioned on the base, a collector trace, positioned on the base next to and insulated from the variable resistor trace. The rheostat includes an actuator, slidably coupled to the base, for sliding over a length of both the variable resistor trace and the collector trace to make electrical contact therebetween. The rheostat also includes a first set of contacts, that are 1) electrically coupled during operation of the rheostat, and are 2) electrically isolated during operation of the switch; and a second set of contacts, that are 1) electrically isolated during operation of the rheostat, and are 2) electrically coupled during the operation of the switch.
