Test buttons (no latching) and plugs
Test buttons (no latching) are recommended for R2...WT, R2N...WT, R3...WT, R3N...WT, R4...WT, R4N...WT,
R15...WT 2 CO, R15...WT 3 CO relays - for appli­cations that do not allow permanent contact latching. By manual
operation (pressing the button) relay contacts can get switched for as long time as long the button is pressed. Contacts
return to initial position as soon as pressure is released from the button. Those operations can be done while the coil
is deenergized.
Button R4P-0001 or R15-M404 can be easily inserted by
the Customer after removal of button type T (see Fig. 2).
Button type T can be removed with screwdriver as shown
on Fig. 1.
