A control mechanism for use with a door closer, comprises a shaft (10), angularly movable between a normal position and a second position, the shaft (10) having a first portion (21a) and a second portion (21b), a brush spring (35) attached to the shaft first portion (21a) to return the shaft to its normal position, and a damping mechanism (36, 38) attached to the shaft second portion (21b) to resist shaft movement to its normal position. The damping mechanism includes a coiled strap-like member (36) keyed to the shaft and contained in a damping medium. |
