Abstract: A control and detector for a railroad switch point having a detector mechanism which is secured to a stockrail at the switch point where the stockrail is intended to be in contact with a corresponding switchrail. The detector mechanism is secured in a housing and has a plunger assembly biased in the direction of the switchrail and reciprocably secured preferably in alignment with the switchrail at the switch point. Electrical contacts connected to the plunger assembly report contact or a lack of contact between the switchrail and the stockrail. A contact on the switchrail at the switchpoint for reciprocates the plunger against the electrical reporting contacts when the switchrail is in physical contact with the stockrail at the switchpoint. A heating element is associated with the switchpoint and us energized in response to contact between the stockrail and switchrail as detected by the detector mechanism.

Abstract: A safety detector for a railroad switch point having a detector mechanism which is to be secured to a stockrail at the switch point where the stockrail is intended to be in contact with a corresponding switchrail, in which the detector mechanism is adjustably secured in a housing located below the stack rail and has a spring loaded plunger assembly normally biased in the direction of the switchrail and reciprocably secured preferably beneath the stockrail in alignment with the switchrail at the switch point, electrical contacts connected to the plunger assembly for reporting contact or the lack of contact between the switchrail and the stockrail, and a contact on the switchrail at the switchpoint for reciprocating the plunger against the electrical reporting contacts when the switchrail is in physical contact with the stockrail at the switchpoint.
