they are switches or contacts of some sort, possobly relating to motor control. can't say i seen them anywhere before.
 
Based on logic and guesswork;

The first, labelled FRI is a normally closed latched contact which is released by the action of something else, for example Overtemperature, Overpressure, Overload.

The middle symbol, the sides of the actuator both point in the same direction, down, indicating that the control of the function is only one way, like a push button.

The final symbol, on the right, similar to the previous one but has bi-directional indication so has control in both direction as a normal On/Off switch would have.
