Push-Push Card Sockets — SD, microSD, SIM

What is a push-push card socket?

A push-push card socket holds the card with a spring-loaded cam: the first push seats and latches the card, a second push ejects it. The latch, not friction, retains the card, so insertion ends with a definite click and removal needs no tool.

When to choose push-push card sockets

Choose push-push for an exposed slot where users insert and remove cards regularly and expect tactile confirmation.
Choose a non-eject (slide-in / slide-out) socket when the card is fitted once and rarely removed, or when the socket must be as low and simple as possible.
Mated height and durability are compared per model in each series parameter table; normal versus reverse orientation is stated in the part description.

Selection FAQ

What is the difference between a push-push and a slide-in / slide-out card socket?

A push-push socket has an eject spring and cam: one push latches the card, a second push releases it. A slide-in / slide-out socket (no eject spring; "Simple Type" or "NON PUSH" in the catalogue) holds the card by contact normal force and the housing walls and is pulled out by hand, with the fewest parts.

Which KINGCONN series include push-push sockets?

11 series, 43 part numbers: CFAST (1); CF express & XQD (2); Micro SD ( T-Flash ) (12); Micro SD 4.0 (4); Micro SD 7.0 & Micro SD 8.0 (3); Micro SIM (2); Mini SIM (2); NANO SIM (3); SD (8); SD 7.0 & SD 8.0 (3); SD 4.0 (3). Every part page has the engineering drawing (PDF).

How do I check the durability (insertion cycles) of a push-push socket?

The specification table on each part page and the parameter table on each series page show the mating cycles stated on the drawing; part numbers whose drawing does not state it show no value — nothing is estimated.

How do I request samples or a quotation for a push-push socket?

Email service@kingconn.com.tw with the part number. Clicking any part card on a product page also pre-fills the enquiry subject with that part number. Our sales team will reply with the drawing, samples and pricing.
