    • A high temperature limit switch is disclosed. The switch includes a resettable temperature responsive mechanism movable between a non-tripped position and a tripped position, a reset member movable between a position of rest and a reset position, a non-movable fixed contact, and a pivotable contact support member including a contact movable with respect to the non-movable fixed contact. The contact support member is configured to prevent the movable contact from engaging the fixed contact while the resettable temperature responsive mechanism is urged from the tripped position to the non-tripped position in response to force applied to the reset member until the reset member is returned toward the position of rest. A method of resetting a high temperature limit switch is also disclosed.
    • 公开了一种高温限位开关。 该开关包括一个可复位的温度响应机构,可在非脱扣位置和脱扣位置之间移动,复位构件可在静止位置和复位位置之间移动,不可移动的固定触点和可枢转的触点支撑构件, 相对于不可移动的固定触点可移动。 接触支撑构件被构造成防止可动触头接合固定触点,同时响应于施加到复位构件的力而将可复位温度响应机构从跳闸位置推到非跳闸位置,直到复位构件返回到 休息的位置。 还公开了一种复位高温限位开关的方法。
