ABSTRACT:
A system for selectively reversing the deflection sweep to a yoke coil of a television receiver system in which a double pole-double throw (DP-DT) switch reverses the current to the deflection coil, a solenoid relay actuates the DP-DT switch, and switch control and arrangement means for energizing the solenoid relay during times when power is not applied to the television receiver system. Also the system provides for a four or more sequential position switch in which intermediate portions of the switch perform as a break-before-make (BBM) stage and the outer portions of the switch positions perform as make-before-break (MBB) stages and the switch comprises a DP-DT and a four position switch operable mechanically in tandem.
