A board holddown (1) for holding circuit boards (8,9) includes an elastomeric support member (10) and a bullet-shape member (20) of more rigid material than the support member. The support member includes a first mounting portion (11) for supporting a first circuit board (8), a second mounting portion (12) for supporting a second circuit board (9), and an elongate, thin neck (13) projecting from the second mounting portion. The bullet-shape member is attached to the elongate, thin neck and includes a latch (21). The elongate, thin neck has substantial resilience so that the second circuit board can be easily detached from the board holddown by pushing the bullet-shape member away from its holding position.
