manner similar to that described with respect to fig6 and 7 in this embodiment the actuator rod 140 will trigger operation of the switches 240 250 and 260 and that the operation of the cam 390 will trigger operational movement of the actuator rod 150 in an alternative embodiment latching apparatus will not have an actuator rod 140 or rotational link 95 and the push rod 90 will extend through the length of the chassis to trigger operation of the switches 240 250 and 260 in this embodiment closed circuit resulting from the push rod 90 contacting the switch or switches will signal the operation of the motor 270 assemblies 5 200 and 500 are constructed in a manner that improves assembly speed in production by reducing the amount of labor and the number of parts that are required and thereby avoiding assembly errors e g wire assembly and mechanical assembly errors which are common in the art assemblies 5 200 and 500 also provide simplified operation as compared with current prior art devices in use for assembly 5 the transmission of transient electrical signals are prevented from affecting the electrical circuit on board 160 additionally assemblies 200 and 500 provide the following benefits first the single point power connection reduces or eliminates wire connection errors in this case it is not possible for printed circuit paths to be connected incorrectly therefore assembly workers and service technicians will not have an opportunity to misconnect the wiring second assemblies 200 and 500 will reduce assembly time in oven manufacturing since the mating wire harness will only have one connector that plugs into the latch third the oven latch connection will install easier and reduce repetitive motion injuries for assembly workers this is.
